Objectives The students have acquired a sound understanding of the foundations of granular mechanics for both systems with and without interstitial fluid phase. They know several models for such systems and know which one is the most appropriate under given conditions. This involves

  • microscopic,
  • mesoscopic and
  • macroscopic

models.

Furthermore, the students are familiar with various numerical methods to use these models in computer simulations. They know their algorithmic properties regarding

  • stability,
  • accuracy and
  • efficiency

as well as important aspects for the implementation of these techniques.

The level of the mathematical treatment corresponds roughly to that of the textbooks (i) Rao, Nott: An Introduction to Granular Flow. Cambridge University Press, 2008, (ii) Ferzinger, Peric: Computational Methods for Fluid Dynamics. Springer, 2002 and (iii) Pöschel, Schwager: Computational Granular Dynamics. Springer, 2005.

Subject Introduction to the physical concepts of particle-laden flows:

  • Navier-Stokes equations for the continuous phase
  • Newton‘s law of motion for macroscopic particles and their mutual interaction
  • Combined description of particle-fluid systems at various scales

Different models and algorithms for the simulations of granular systems and particle-laden flows:

  • Discrete element method (DEM), e.g. using the velocity-Verlet algorithm
  • Computational fluid dynamics coupled with discrete elements (CFD-DEM), e.g. using the PISO algorithm
  • Two-fluid model (TFM)
